Optics & Thin Films Capabilities

HHV LTD

OPTICS FABRICATION
HHV’s precision Optics Fabrication Lab is equipped with state-of-the-art technology and machinery to fabricate high precision optical components in the visible and infrared spectrum. 

OPTICS MATERIAL AND PRECISION
HHV has extensive knowledge on handling materials such as Quartz, Fused Silica, Zerodur, BK7, Crown and Flint Glasses for the                                                                                            andSilicon, Germanium, Zinc Sulphide for the Infra-Red spectrum.

OPTICS METROLOGY
1. ZYGO Interferometer with transmission spheres to measure surface figures up to 1/10th lambda
2. Trioptics Spherometer  to measure the radius of curvature of various components to an accuracy of one micron
3. Davidson Autocollimator to measure the surface angles and parallelism to an accuracy of less than one arc second
4. Talysurf PGI Freeform allows for high resolution measurement of high precision freeform optics. 

OPTICAL COATINGS
HHV’s Thin Films production facility has over twenty five systems with accessories and processes that are clean room compliant. HHV can handle substrate sizes of upto 1000 mm for thermal ,sputtering deposition processes.

COATING TECHNOLOGY
1. Magnetron Sputtering systems
2. Ion-Assisted E-Beam Deposition systems
3. Resistance Evaporation systems
4. Plasma Enhanced Chemical Vapour Deposition systems
5. Atomic Layer Deposition systems

HYBRID MICRO CIRCUITS

HHV’s Hybrid Micro Circuit (HMC) Lab is approved by ISRO for the production of Flight Mode components. HHV develops and produces metallized and patterned alumina substrates for space and defence applications. The HMC Lab produces multi-layer metallization using Chromium, Copper, Gold, Nickel, TiW, Pt and NiCr and achieve resolutions up to 10 microns.
